the coolest (uh, literally)
so tracy and i have kept up a little tradition of taking short walks in the morning before we start work. we usually walk around the neighborhood or nearby - yesterday, we walked down to the town of pittsboro building to pay our water bill. just after we stepped out our front door, we noticed something strange surrounding the reflecting pool. amazing formations of ice, little springs of water that had pushed themselves up through the dirt and the hay. crazy little things. they look a bit like eyelashes. can anyone explain?

This beautiful phenomena of yours, my dear, is ground ice that has exceeded the "pore ice" volume within the soil ... thereby causing "creep ice", and/or if the pore water has migrated and then froze within a frozen soil, it forms "segregated ice" due to a certain soil micromorphology... ah hum... This results in distinct patterns of frost and thawing processes: Orbiculic, suscitic and conglomeric fabrics are coarser soil particles which form circular to ellipsoidal patterns (orbiculic), vertical or near-vertical orientation (suscitic), and compound arrangements (conglomeric), probably as a result of cryoturbation activity. Segregated ice results from cryosuction, not cryoturbation. A bit of needle ice may have occured as well, if you had granic or granoidic fabrics making up yo soil. Needle ice forms under rocks, soil peds, moss, and vegetation. Each formation lovely, yes. I will elaborate on these terms and processes if it shall please you... hee, hee, hee.....
Lovingly, Yo Sister
